A fluid tank and an expansion vessel are separated from one another by a planar wall portion having two openings communicating with the fluid inlet and outlet compartments, respectively. A coupling device cast en bloc includes a stopper that plugs an opening of the expansion vessel, and two fluid inlet and outlet necks penetrate the stopper and have respective openings that coincide with the openings of the two respective chambers.

The fluid tank includes two coaxial necks. The inner neck is defined by a longitudinal portion of a partition that also includes at least one transverse portion dividing the fluid tank longitudinally into two chambers for the inlet and outlet of fluid. A rapid coupling device cast en bloc includes two coaxial necks cooperating respectively with the necks of the fluid tank, to couple the chambers to an external circuit.

The invention relates to a method of manufacturing a fin for a heat-exchange module which comprises at least two heat exchangers equipped with fluid-circulation tubes and comprising cooling fins common to the exchangers. The fin consists of a metal strip (14) having a width (L1) divided into at least two heat-exchange regions (18, 20) by at least one series of longitudinal oblong holes spaced apart from one another. In accordance with the method of the invention, at least one series of longitudi...

The invention relates to a front panel of a motor vehicle comprising a bumper beam and at least one heat exchanger. This heat exchanger (5) is located below the bumper beam (3) with a substantially vertical orientation and comprises, in a horizontal plane, an upper face having a shape similar to the shape of the bumper beam (3) such that the upper face is covered by the bumper beam (3).

A manifold for, e.g. a motor vehicle heat exchanger, has a first part formed from a shaped metal sheet and bottom and two lateral walls folded face-to-face, at least one of which is provided with an aperture for fixing a pipe there. A second part is shaped metal sheet and able to be fitted onto the lateral walls of the first part to form a cover opposite the bottom of this first part. Either the first part or the second part has a manifold plate. The first part, the second part and the pipe are ...

A control valve (10) for a fluid circulation circuit comprises a body (12) which is equipped with a fluid inlet (18) and at least two fluid outlets (20, 22 and 24) and which delimits a cylindrical housing for an adjusting member (26) able to rotate about an axis of rotation (XX) and to adopt various angular positions in order to control the distribution of fluid through the outlets. The body (12) comprises an end wall (14) into which the fluid inlet (18) opens and a cylindrical side wall (16) in...

A coupling device for a handling trolley comprises a drawbar (22) arranged at the front of the trolley and designed to co-operate with the hook (24) provided at the back of a tractor, in particular a trolley preceding a line of trolleys. The drawbar (22) comprises a longitudinal slot (36) wherein the hook (24) is designed to slide such that the hook can slide in the longitudinal slot between a position spaced apart wherein the trolley (10) is at a maximum distance from the tractor while it is be...

The invention relates to a hydraulic circuit element (20) for heat exchange between a first fluid and a second fluid, which defines a path for the first fluid and comprises at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one communicating passage (28b) that defines the path of the first fluid. The invention also relates to a heat exchanger obtained by stacking circuit elements (20). Such a heat exchanger can be used ...

The invention concerns a tube (1) internally divided into two longitudinal channels (16) by a median spacer (9). In an end zone (4) penetrating a fluid box (19), the tube is deformed so as to be widened in its transverse section and shortened on either side of the spacer in the direction thereof. The space requirement of the fluid box in the longitudinal direction of the transverse sections of the tubes, and consequently the space requirement of the whole heat exchanger, can thereby be reduced r...

A side member for a heat exchanger has a portion which is adapted to preferentially break under low tension to alleviate problems caused by expansion, whilst retaining integrity under normal transport movements.
